Ikoreshwa
Ifu ya kirisiti yera
Amashanyarazi yera, kristaline cyangwa ifu ifite impumuro iranga.G imwe ishonga mumazi agera kuri 30 mL.Irashobora gushonga muri acide acide no mubisubizo bya hydroxide ya alkali.Irashobora gushonga cyane muri alcool, kandi ntigishobora gukemuka muri ether.Ntabwo ikora neza.PH ya 1 kuri 100 igisubizo kiri hagati ya 5.6 na 6.1.Iyi ngingo irashobora gutegurwa hiyongereyeho methanethiol kuri acrolein;no guhinduranya imiti ya methylthiopropionic aldehyde.
d, l-Methionine ifite impumuro iranga.Ni aside amine yingenzi kandi ikoreshwa nkintungamubiri nintungamubiri.
Umusaruro wibintu bihindagurika bijyanye nuburyohe bwibiryo biva muri Strecker kwangirika kwa DL-methionine.Kwiyongera kwa methionine muburyo bukwiye kuri ibyo biribwa bishobora kuba byitezwe kuzamura proteine.Mu bukungu, DL-methionine byaba byiza.Acide yingenzi idafite aside irike ifite imbaraga zo kwirinda okiside.DL-Methionine rimwe na rimwe itangwa nkinyongera ku mbwa;ifasha kurinda imbwa kwangiza ibyatsi mugabanya pH yinkari.Methionine yemerewe nk'inyongera ku biryo by'inkoko kama muri gahunda yemewe na Amerika.
